Being one who does no camping with hookups, the Suburban forced air
furnace we had worked great until the
battery drew down to about 11 volts then the
furnace would not fire.
So during a complete remod, I put a wave three in...and took it out after one trip. Could not stand in front of it to cook, or brush your teeth, or anything else.
Then I put in this:
Force 10 Cozy Cabin heater---
no
battery to draw down, burns about 1 pound of
propane on high setting in 8-10 hours.
Has a safety shutdown when air qualit gets below 98% of normal
oxygen...
I like it---made for sailboats---about $450 five years ago.
